Sales Manager — Scientific Instrumentation (Quantum SPM)

About Onnes Technologies

Onnes Technologies is a deep tech company pioneering innovation in Quantum Scanning Probe Microscopy (qSPM), with a focus on cryogenic tools that enable breakthroughs in low-temperature physics, quantum computing, and nano-electronics.

Notable products include:

• CRYO-WALKING nanopositioner (arQtika): The first and only walking piezo technology designed for ultra-low temperatures.
• Cryogenic vibration isolation for cryogen-free dilution refrigerators (ZeroSpring): A groundbreaking tool enabling the application of Scanning Probe Microscopy in cryogen-free dilution refrigerators.

As Sales Manager you will help lead the commercialization of our cryogenic instrumentation and contribute to the strategic revenue growth of both product lines.

Your Role

You’ll be at the forefront of our growth — building trusted relationships with scientists and research institutions worldwide and ensuring our innovations reach the labs where they’ll have the most impact. You’ll own sales targets, shape our commercial strategy, and represent Onnes Technologies at international conferences, while keeping a close feedback loop with our product and engineering teams.

Key Responsibilities

• Own and deliver sales targets while building long-term relationships with leading research groups worldwide.
• Develop a deep understanding of the cryogenic instrumentation science landscape and gather continuous customer insight.
• Drive product sales and visibility in the scientific community by exhibiting at conferences and visiting key leads.
• Build strong relationships with labs, institutions, and distributors — both to gather product feedback and expand commercial collaborations.
• Further professionalize the sales processes – from lead generation, to order intake, to after-sales.
• Mentor junior team members involved in (after) sales tasks.
• Contribute to future products in the cryogenic instrumentation space (e.g. on topic of Quantum Metrology).

About You

• Degree in Physics or related field (BSc/MSc or equivalent).
• A hands-on sales leader with a proven track record of revenue generation in the field of scientific equipment.
• Able to apply your expertise by introducing sales organisation best practice to shape a growing Sales Team.
• Strong communication and interpersonal skills.
• Willingness to travel.
• Highly self-driven, proactive, and comfortable taking ownership.
• Familiarity with scientific instrumentation, ideally in SPM, or cryogenic systems

Bonus Points

• Direct experience with LT-SPM, or related experimental setups.
• Prior exposure to startup or scale-up environments in deep tech or scientific tools.

Team and Culture

At Onnes Technologies, we’re a tight-knit team of around 20 people united by a passion for innovation and scientific discovery.

We operate with a flat hierarchy, encouraging initiative, self-drive, and ownership. Everyone has a voice, and decisions happen fast. It’s a collaborative, hands-on environment where you’ll be empowered to take ideas from concept to reality.

Our work is deeply technical and benefits from close, day-to-day interaction, so we’re primarily office-based. That said, we envisage a hybrid setup for this specific role. We maintain a flexible and supportive atmosphere that values focus and autonomy.

As a young and growing deep tech startup, there’s real opportunity to shape your role, grow into new responsibilities, and make a visible impact. In this role especially, you’ll work directly with leading scientists and researchers from around the world, helping bring groundbreaking tools into their labs.

Why Join Us?

• Be the face of a pioneering deep tech company to the global research community.
• Work in an entrepreneurial and collaborative environment with room to grow.
• Travel internationally to engage with leading scientists at the frontier of quantum technologies.
• Competitive compensation and the opportunity to shape the future of the company.
